/****************************************************************
The abacus class is useful today for debug purposes, but it
will eventually serve as the implementation for css counters.
This implementation is fine for static documents, but woefully
inadequate for dynamic documents. (This about what happens if
someone inserts a new counter using the DOM? -- The other
numbers in that "group" should be renumbered.)
In order to be dynamic, we need a counter "group" manager that
is aware of layout (geometry at least) -- and that has a
mechanism for notifying markers that need to be updated, along
with the ability to cause incremental reflow to occur in a
localized context (so the counters display correctly).

/****************************************************************
The abacus class is useful today for debug purposes, but it
will eventually serve as the implementation for css counters.
This implementation is fine for static documents, but woefully
inadequate for dynamic documents. (This about what happens if
someone inserts a new counter using the DOM? -- The other
numbers in that "group" should be renumbered.)
In order to be dynamic, we need a counter "group" manager that
is aware of layout (geometry at least) -- and that has a
mechanism for notifying markers that need to be updated, along
with the ability to cause incremental reflow to occur in a
localized context (so the counters display correctly).
